Description

Leaching tests with water and brines were conducted on AC 6120 iodine sorption material (12 wt.% Ag) in order to improve the assessment of the behaviour of radioactive waste stored in a repository mine (salt or iron ore). As a result of the dynamic and static leaching tests, the leached fraction of I-129 in the uncemented material was found to be < 10-1%, while that of the cemented iodine sorption material was found to be < 10-2%. After ordinary steel had been added to the cemented sorption material, the leached fractions found were identical to those measured in uncemented material. The addition of stainless steel had only little influence on the leached fraction. (author)
